The Yankees better land Cliff Lee or else they could be in a world of hurt next season.

Offensively, they’ll continue to be dangerous. Thanks to Alex Rodriguez, Mark Teixeira, Robinson Cano, Curtis Granderson, Derek Jeter, Nick Swisher and Jorge Posada, they won’t have to worry about scoring runs again next season (although it’s important to note that Jeter is coming off a career-low year and Posada struggled at the dish as well.)

But their offense wasn’t the reason they fell short of reaching the World Series: their pitching was. That’s why they set out this offseason to acquire Lee, but there’s no guarantee that they’ll be able to land him with the Rangers trying desperately to retain him.

After Jayson Werth and Carl Crawford each received seven-year contracts, the Yankees had no choice but to add another year to their offer for Lee. They wanted to stay at six years, but the Rangers have amped things up and are reportedly sending a contingent to Arkansas on Thursday in order to get Lee to re-sign. The Yankees had no choice but to take an at-all-costs approach in signing the 32-year-old ace.

Chances are Texas won’t be able to match New York’s final number, which is good for the Yankees. But Lee enjoyed playing with the Rangers last year and spoke after the World Series as though he was coming back. If Texas can get close to the Yankees’ asking price, then Lee may re-sign with the Rangers in order to stay in familiar surroundings.

That would be devastating for the Yankees, who now are suddenly looking up at the Red Sox in the AL East. Just this past week, Boston traded for slugger Adrian Gonzalez and signed Crawford to a whopping $142 million deal. Instantly the Red Sox have added power, speed and defense to their roster, all while the Yankees have impatiently waited for Lee’s answer. If they can’t sign Lee and they go into next year having to rely on A.J. Burnett being one of their top arms, the Bombers are in trouble.

They may want to add on an eighth year if that’s what Lee wants.
